Private Communication Systems
The keypad (1020), the loudspeaker (1120), the microphone (1110), the dust
protection frame (1190) and the microphone gasket (1220) are mounted into the
upper case shell (1030). Make sure that the microphone contacts are properly bent
up when mounting.
When turning in the screws (1070, 1080) make sure that the right torque is used (25
Ncm), because this will have an effect on the funtionality of the handset.
The only removable part on the user interface is the ringer gasket (1170) which is
needed to increase the ringer volume.
